[PATCH] D141576: [CodeGen] Prevent overlapping subregs in getCoveringSubRegIndexes

[Pierre van Houtryve via Phabricator via llvm-commits]

Pierre-vh added a comment.

Testing for this is a bit tricky, fortunately it looks like it's already covered by a test.
If another form of testing is needed, perhaps we could do a unit test? I feel like it'd be a lot more straightforward to just query TRI in a unit test and check all the corner cases there.
